Block off one-third of a soccer net with a cone, 5-gallon bucket or some other suitable object. Shoot into the smaller side from a set distance, but systematically varying the angle to the goal line. Take enough shots at each angle to get a reliable sample. How does success vary with angle? For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to…

Take shots at a set distance from the basket, but systematically vary the angle to the backboard. For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to illustrate your conclusion. For a more advanced project: Use your knowledge of geometry and basketball to come up with a mathematical expression to predict your success rate as a function of angle…

If you like to play Tetris, then you might like this project. You will learn something interesting about the mathematics of complex shapes as you try to prove Pick's Theorem.
The strange shape below is an example of a lattice polygon, which is a polygon whose vertices lie on points in the plane that have integer coordinates.
As you can see, it is a complex shape, but there is an easy way to calculate its area, by simply counting lattice points!
If you count the number of lattice points on…

Can you remember what the weather was like last week? Last year? Here's a project that looks at what the weather was like for over a hundred years. You'll use historical climate data to look at moisture conditions in regions across the continental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison. Which part of the country has the most frequent droughts? The most frequent periods of prolonged…

Learn how to edit sound files so that you can manipulate the recorded sound mathematically. You can either find specialized audio editing software or do background research to teach yourself about sound file structure so that you can write your own simple program to manipulate sound files. Try arithmetic operations on the sound values (e.g., adding or subtracting a constant, multiplying or dividing by a constant). How do these operations alter the sound? Try other mathematical operations:…

In this project you'll make a liquid that will contradict your expectations. Hold it loosely in your hand and it will drip off your fingers, but grab it tightly and it will feel solid. Slap a bowl of it with a spoon, and instead of splattering, it solidifies. Do background research on colloids, and be sure you can explain the following terms: colloid, Newtonian fluid, non-Newtonian fluid, thixotropic. (For instructions on how to make it see the link listed under Exploratorium, 1998, in the…

Students who are mathematically inclined can use the student version of a program like MatLab or Mathematica to convert a digital image into numbers, then perform operations such as sharpening or special effects. This is a great way to learn about image processing algorithms.

How accurately can people identify the location of a sound source when blindfolded? Imagine the hemisphere of space that extends above your shoulders at arm's length. Divide that hemisphere up into regular sectors and test the ability of blindfolded test subjects to point to a remembered sound source. For example, you could use the beep from a timer held at each test location, and then have the test subject point to where they think the timer was located. Record the magnitude and direction of…

Music has many mathematical elements in it: rhythm, pitch, scale, frequency, interval, and ratio. There are many ways to turn these elements into a science fair project. You can investigate how the scale is based upon a special type of number sequence called a Harmonic Series. Another scale used by Bach, called the "Well-Tempered-Scale" or the "Equal-Tempered-Scale", is based upon a series. How are these mathematical series and ratios related to notes, chords, intervals, and octaves? You can…
